Hello pesky web platform-lack-of-functionality savior.
As a marketing pro obsessed with e-comm I jump on any new deal, free trial or platform launch I can find to take store builders, CMS or SaaS for a spin. Since no platform offers every function, we find ourselves torn between options. Here is one powerful solution.
Powr.io 
Holy man you guys, Powr.io is a time saver. It creates code that plugs into your current web platform for to create custom web forms, Social Media feeds, polls, countdowns, PayPal buttons... You name it. And they take requests to develop any function you desire. So when you find that perfect Shopify template but if doesn't have a must-have function for you, just create your custom changes in Powr.io, and it plugs right into the Shopify platform.
A non-web developers dream.
You create the changes you want; web forms, template changes, music players, photo editing... and it not only pumps out the code for you, it tells you how to plug it in. Customization. Click, zip, done.
Darn near total compatibility.
Powr.io is compatible with 99.9% of CMS, site builders and online store creators. 99.9% Even Social Media platforms like Blogger, Facebook and Tumblr. Mmmmm Tumblrrrrr....
Reasonably priced.
Get lots of functions Free. For more powerful options a very reasonable $2.39 to $39.99 (for functions galore). Use your custom functions on multiple sites.
If you're considering changing your current CMS or site builder in search of increased functionality, save yourself some dough and lots (really lots) of time and potential frustration, and look to Powr.io to add the non-native functions you seek.
